MACHINE FOR SHAPING 'SHOE-SOLES.

' SPECIFICATION forming part of Letters Patent No. 347,050, dated August10, 1886. T 1

Application filed June 1, 1886. Serial No. 203,708. (No model.)

To all whom it may concern:

Be it known that I, OSCAR FITZALAN KNoX, of lVatertown, in the county ofMiddlesex, of the Common wealth of Massachusetts, have invented a newand useful Improvementin Machinery for Shaping the Soles of Shoes orBoots; and I do hereby declare the same to be de scribed in thefollowing specification and represented in the accompanying drawings, inwhich- Figure 1 is a longitudinal section, and Fig. 2 a transversesection in part, of a machine embodying my invention, the nature ofwhich is defined in the claim hereinafter presented. Fig. 3 is a sectionof the cam P that operates the shoe-heel holders or levers to beexplained.

My invention has reference to mechanism essentially as represented anddescribed in the United States Patent N 0. 164,235, it being, as thereinstated, for beating out the soles of boo -s or shoes. I

The aforesaid drawings show the special portions of such machine, towhich is applied the mechanism, hereinafter described, for preventing ashoe from slipping on its last while such shoe may be acted on by one ofthe pressingformers.

In the operation of such machine the shoe is very apt to rise or slip atits heel upward on the last while the shoe may be in the act of passingthe channel laying chains or one of the formers,'it being very desirableto keep the shoe close down upon the last while the sole of such shoemay be in the act of being shaped, otherwise the sole will not have itstrue form lengthwise of it, and the instep of the upper is liable tobecome stretched. V

In carrying out my invention I combine with the mechanism for beatingout the soles mechanism for holding the shoe from slipping upward on thelast at. the heel thereof, while the shoe may be under the action of oneof the formers.

In the drawings, A A A, 850., represent the series of lasts on which theboots or shoes are to be held in order to have their solessmoothed andshaped by the rubbing belts or chains 0 The lasts are mounted on radialarms G, projecting from a disk or hub, H, carried by a revoluble shaft,

I. This shaft, by gears L and M, is connected with another shaft, J, onwhich is a wheel, N, to whose periphery the two pressingformers E arefixed and from which. they extend, as represented.

. a To a sleeve, 0, encompassing and fixed on sleeve and over a cam, P,that is stationary at the outer end of the sleeve and supported by themachineframe. This cam is shown in longitudinal section in Fig. 3.Aspiral spring, Q, encircles the several shorter arms of the levers Rand draws them in contact with the periphery of said cam, and while anyof such short-er arms may bear against the circular part of suchperiphery the longer arms connected with them will be borne out ofcontact with the shoes on the lasts. \Vhile, however, any one of theshoes may be in process of be ing acted on by one of the formers E, theprotruding part c of the cam will be in action on the lever or holder ofthe said shoe, and will force it up to the shoe, so as to prevent suchshoe from slipping upward upon the last.

\Vhile an attendant may be either removinga shoe from one of the lastsor applying another thereto the holder next adjacent to such last willbe back or away from the last sufficiently to be out of the way of theshoe.

I do not claim in combination with a last and presser, arranged andprovided with mech anism for simultaneously reciprocating them, asrepresented and described in the United States Patent No. 296,486, a rodand a spring applied to the lastcarrier, and being to hold a boot orshoe on the last, so as to prevent such boot or shoe from rising thereonwhile prcssure is .by the presser being applied to the sole at the toeportion thereof, my invention ha"- ing reference to a machine having arevoluble series of lasts that all rotate simultaneously in l r I onedirection under and operate in connection with a revoluble presser orpressers.

I claim-- The combination, with the revoluble series 5 of lasts and oneor more revoluble pressing former or formers having mechanism forrevolving them, as explained, for beating out the soles of shoes orboots applied to such lasts, of mechanism, substantially as described,10 for preventing each shoe while subjected to the action of apressing-former from slipping or rising upon the last, such mechanismbeing the series of angular levers, and their acluating-spring and cam,arranged and to operate essentially as set forth.
